I agree Fred.  I've soaked ivories that I have saved from keytop
replacement jobs in hydrogen peroxide solution for a week to remove epoxy
and other nasties.  Some of them actually slowly disintegrated to
powder.  Others looked like a badly weather beaten piece of wood.  I've
never had them suffer any ill effects using the proceedure I posted.  The
event is probable though.

The best ivory seems to be on old Steinways.  Thick, excellent quality,
attractive graining, durable, and very responsive to whitening.  Thin,
badly curled ivories with perhaps lots of cracks, I don't waste my time
or the customer's money whitening.
